Day 39 and she got two gallons of 10ml cal/mag per gallon at 6.8 ph. I know this sounds dumb but I just read the label on Sensi cal/mag extra (last two pics) and it is not listed for soil, just hydro and foliar. The old Sensi cal/mag plus was. Could this stuff not be working? Anyway this light is great, the interior buds are about twice as big and thick as under the old 100X3. Bud development and resin production is good. The ph issues will end this grow a bit early, I guess about the first week of next month. The led is at 12 inches.
